Our 15 year old wants to take a friend with her which I understand. We will be traveling with stepdaughter 23, stepdaughter 26, her husband and 2 year old son. We have always included the 23 year old on our vacations because she still lived at home and was under our care while in college. With the other family going my daughter will be left out and wants a friend with her. I'm wondering how others have handled the expense of inviting a friend along to Disney. The few times we have allowed friends to our beach trips we have covered all the expenses - which was just food since the condo was already rented. Disney will be a lot more expensive than a beach trip. I feel that we should cover that since we are inviting, but on the other hand, it is very expensive to cover. What do you do?
